Pre-heat your oven to 350 degrees.

Clean the mushrooms and remove the stem. Place them bottom side up on a baking dish and drizzle them with 2 tablespoons of olive oil. Put about 1 tablespoon of brie into each of the mushroom cavities.

In a small bowl, combine the rest of the ingredients and about 2 tablespoons of olive oil and season the mixture with salt and pepper. Fill the mushroom cavity with a small scoop of the bread crumb mixture.

Transfer the baking dish to the oven and bake for about 20-25 minutes until the mushrooms are tender and then cheese is melted.

Remove the baking sheet from the oven and serve.
